Since I read a lot of really OLD books, I have found that, no matter the field of study, anything that leads to man being able to improve his own condition gets suppressed in favor of a far less effective, but far more profitable system. So is the case with Anton Mesmer, whom, in the 18th century, documented the astrological effects of planets on people, as well as coming to a comprehension of prana / Qi. This list comprises the 27 propositions he made, concerning "animal magnetism" (which isn't actually about sex...!):

Propositions Concerning Animal Magnetism by Anton Mesmer, 1779

A responsive influence exists between the heavenly bodies, the earth, and animated bodies.

A fluid universally diffused, so continuous as not to admit of a vacuum, incomparably subtle, and naturally susceptible of receiving, propagating, and communicating all motor disturbances, is the means of this influence.

This reciprocal action is subject to mechanical laws, with which we are not as yet acquainted.

Alternative effects result from this action, which may be considered to be a flux and reflux.

This reflux is more or less general, more or less special, more or less compound, according to the nature of the causes which determine it.

It is by this action, the most universal which occurs in nature, that the exercise of active relations takes place between the heavenly bodies, the earth, and its constituent parts.

The properties of matter and of organic substance depend on this action.

The animal body experiences the alternative effects of this agent, and is directly affected by its insinuation into the substance of the nerves.

Properties are displayed, analogous to those of the magnet, particularly in the human body, in which diverse and opposite poles are likewise to be distinguished, and these may be communicated, changed, destroyed, and reinforced. Even the phenomenon of declination may be observed.

This property of the human body which renders it susceptible of the influence of heavenly bodies, and of the reciprocal action of those which environ it, manifests its analogy with the magnet, and this has decided me to adopt the term of animal magnetism

The action and virtue of animal magnetism, thus characterized, may be communicated to other animate or inanimate bodies. Both of these classes of bodies, however, vary in their susceptibility.

Experiments show that there is a diffusion of matter, subtle enough to penetrate all bodies without any considerable loss of energy.

This action and virtue may be strengthened and diffused by such bodies.

Its action takes place at a remote distance, without the aid of any intermediary substance.

It is, like light, increased and reflected by mirrors.

It is communicated, propagated, and increased by sound.

This magnetic virtue may be accumulated, concentrated, and transported.

I have said that animated bodies are not all equally susceptible; in a few instances they have such an opposite property that their presence is enough to destroy all the effects of magnetism upon other bodies.

This opposite virtue likewise penetrates all bodies: it also may be communicated, propagated, accumulated, concentrated, and transported, reflected by mirrors, and propagated by sound. This does not merely constitute a negative, but a positive opposite virtue.

The magnet, whether natural or artificial, is like other bodies susceptible of animal magnetism, and even of the opposite virtue: in neither case does its action on fire and the needle [of a compass] suffer any change, and this shows that the principle of animal magnetism essentially differs from that of mineral magnetism.

This system sheds new light upon the nature of fire and of light, as well as on the theory of attraction, of flux and reflux, of the magnet and of electricity.

It teaches us that the magnet and artificial electricity have, with respect to diseases, properties common to a host of other agents presented to us by nature, and that if the use of these has been attended by some useful results, they are due to animal magnetism.

These facts show, in accordance with the practical rules I am about to establish, that this principle will cure nervous diseases directly, and other diseases indirectly.

By its aid the physician is enlightened as to the use of medicine, and may render its action more perfect, and can provoke and direct salutary crises, so as to completely control them.

In communicating my method, I shall, by a new theory of matter, demonstrate the universal utility of the principle I seek to establish.

Possessed of this knowledge, the physician may judge with certainty of the origin, nature, and progress of diseases, however complicated they may be; he may hinder their development and accomplish their cure without exposing the patient to dangerous and troublesome consequences, irrespective of age, temperament, and sex. Even women in a state of pregnancy, and during parturition, may reap the same advantage.

This doctrine will finally enable the physician to decide upon the health of every individual, and of the presence of the diseases to which he may be exposed. In this way the art of healing may be brought to absolute perfection.

I am also trying to find an English translation of his paper, "On the Influence of the Planets upon the Human Body" (1776), if anyone happens to find one.
